According to the present invention, the following effects can be obtained as a result of employing the above configuration. Since the opening closing member has a specific structure, the non-combustibility is improved, and furthermore, the pipe and the bottom surface of the floor slab (or the metal structural material disposed on the lower surface of the floor slab) can be easily and quickly fitted and adhered. Thus, the opening between the floor slab (and the metal structural material) and the pipe can be closed, the speed and reliability of the installation can be improved, and the construction cost can be reduced. That is,

(1) Since it is made of a non-combustible material, it is not necessary to remove the opening closing member after the opening closing operation is completed, so that the speed of construction and the construction cost can be reduced.

(2) The opening closing member is formed in a flat plate shape which is adapted to the bottom surface of the floor slab (or the metal structural material) and the pipe so as to be adhered to both, and the opening between the pipe hole and the pipe. Preparatory work before mounting, such as dividing the shape required to close the entire bottom surface of the part and partially cutting it out, is simplified.
Furthermore, the bending strength can be increased by inserting the side opposite to the fixing side in reverse, so that the fitting can be easily adjusted based on the fixing point. In addition, it has an advantage that it has a bulky shape, is easy to transport, and can reduce distribution costs.

(3) The opening closing member may be bisected by a line connecting diagonal lines of a square plate, an isosceles triangular shape, a rectangular plate shape obtained by dividing the square plate into two by dividing lines, or a rhombic plate by dividing lines. 2
Since it is formed into a shape that is necessary to close the entire bottom surface of the pipe hole and the opening of the pipe, such as a divided triangular plate shape, it is formed in a divided shape, so it can be polymerized at the overlap margin in construction There is an advantage that the construction is easy and quick, for example, the bending guide portion is easy to bend, and is adapted to the pipe and the bottom surface of the floor slab and easily adhered to both. In particular, since the work is generally complicated and dangerous on-site work becomes easy and quick, the effect is great.

(4) In the opening closing member, the bending guide portion is formed in advance from a large number of perforated cut portions in accordance with a large number of sizes, and a cut line is formed in accordance with each perforated cut portion. Since it is formed alternately, the bending guide can be bent and formed in advance according to the size of the pipe outside the site as a preparatory work. There is an advantage that only the adaptation is required, and the construction can be performed reliably and quickly.

(5) The opening closing member can be formed by bending one of the perforated cut portions of the bending guide portion in accordance with the size of the pipe so that it can be in close contact with the outer diameter of the pipe. Without having to prepare and use a large number of sizes for each outer diameter size, one can be adapted to many sizes of piping with one thing, the size to be prepared is reduced as much as possible, inventory management This has the advantage that the operation can be simplified and the management cost can be reduced.

(6) Since the opening closing member can be easily and appropriately adhered to the pipe and the bottom surface of the floor slab (or metal structural material), the appropriate adhesion between the pipe and the bottom surface of the floor slab (or metal structural material) is ensured. The opening between the pipe and the floor slab (and metal structural material) can be securely closed by carrying a blocking material such as mortar. Even in the event of a fire or earthquake, the fire or earthquake There is an advantage that an unexpected situation due to the above can be surely prevented.

(7) Since the portion corresponding to the overlap margin initially becomes substantially elliptical and approaches the perfect circle of the pipe shape as it is fitted, the contact pressure on the pipe increases compared to the conventional simple butting method. To prevent the plugging material from flowing out. In addition,
By bonding the entire fitting portion or fixing the opposite side to the fixed side, the shape is stabilized, the product can be integrated on site, the construction period can be shortened, and the performance can be significantly improved.

(8) By forming an indicating line having the role of a measure, it is possible to easily cut it by guiding the indicating line to use it after cutting it to a required size on site.
